我是2013年下旬匯錢過去的 當時大約一百萬頭台幣轉美金 然後分十二期去買vti veu 因為怕麻煩 從來沒退過稅 也沒報過稅 然後剛才發現原來表格每隔一陣子就要更新 不曉得有無過期 我查看hc愛筆記部落格 https://goo.gl/8VxVMu 提到「 TD 網銀 => Message Center 」會有訊息 可是我看到的是空的 但剛收到td的信 還好我有看 內容如下： important tax notice-please respond a regular review of our record shows that the name and/or tax identification number（TIN）we have on file for your account ending in 8804 does not match THE internal revenue service（IRS）records,or that our records may be incomplete.（your TIN may be either a social security number or an employer identification.） this can happen for a number of reasons.we want to work with you to determine which one applies,and help you resolve it.if you don't take action and correct this problem,you may be subject to a penalty of up to$100 by the IRS for failing to give us your correct name/TIN combination. please see which of these circumstances best describes your situation, then follow the instrucetions to update your information. 接下來是substitude form w-9-request for taxpayer identification number and certification 請問要填這個表嗎？爬文是不是外國人不該填這個？該怎麼處理呢？ 非常謝謝大家
